Objectives

• Define a simple multicast deployment option
  to work in the PMIP world as we know it
• Comply to
• Existing protocols (PMIP Multicast)
• PMIP deployment perspective
• Use lightweight standard components
• Allow for as much traffic aggregation as
  possible within the scope of current specs

Summary Outcome

• Proposal natural to PMIP deployment
• MLD proxy well adopted lightweight
• Traffic flows/aggregation may be optimal, but
  need not be
• In the presence of native multicast routing at
  MAGs, direct routing is favorable option
• Proposal to WG
• Adopt as WG item when merged with direct routing
  option from draft-sijeon-multimob-mms
